Incumbent Sen. James Lankford's Class 2 seat faces no reelection in 2026; the market tracks the open Class 3 contest triggered by Markwayne Mullin's March 23 resignation to serve as DHS Secretary under President Trump, with Gov. Kevin Stitt appointing interim Sen. Alan Armstrong, ineligible to run. Rep. Kevin Hern leads the crowded Republican primary field ahead of June 16 voting—with Trump endorsement, backing from Sens. Lankford and Scott, and over $8 million raised—cementing trader consensus at 93.5% for a GOP victory in this Solid Republican state per Cook Political Report. Fragmented Democrats, weak fundraising, and Oklahoma's R+20 partisan lean sustain the lopsided odds, though a primary upset yielding a flawed nominee or national wave could challenge it.
